Darren Rowse over on Problogger has posted a poll on how much income bloggers are making from adsense per monthy, on average.

Unsurprisingly, a huge number are making very little from adsense, to the tune of a few cents per day. There seems to be a fair spread over the incremental amounts, and then a surprising jump upwards in the +$10,000 category. Perhaps discounting 25% of those votes as being people living in a dream world, its still a number that many people will be jealous of.

As many people have picked up on, the stats themselves need to be put in context to get a true picture of what they mean. The following would be beneficial (in no particular order):

• Number of blogs/websites using adsense
• Blog niche
• Length of time Blog has existed
• Frequency of updates
• number of authors on the blog
• Other advertising stream sin use
• growth of income over time
• number of adverts per page vs. page length
• total number of pages the blog contains

With the above answered, it may be possible to map out a common trend amongst all the high earning sites. To take a wild stab in the dark, I would guess that the blogs earning $10k+ a month have niche sites that rank well in google/yahoo/msn, that have regularly updated/added content, and have existed for over two years.

Any site that is earing $10k+ a month is not well established is likely to be unable to maintain the income level long term.
